ABSTRACT

THIS INVENTION RELATES TO TERPOLYMERS CONTAINING (A) 2 TO 60 WEIGHT PERCENT OF AN OLEFINIC UNSATURATED HYDROCARBON COMPOUND, (B) 40 TO 98 WEIGHT PERCENT OF A VINYL TYPE COMPOUND HAVING THE FORMULA CH2=C(-R1)-R2 WHEREIN R1 IS HYDROGEN, METHYL OR HALOGEN AND R2 IS HYDROGEN OR A CARBONYL TYPE RESIDUE SUCH AS -COOR3 OR -OCOR4 WHERE R3 IS AN ALKYL RADICAL HAVING 1 TO 12 CARBON ATOMS, AND R4 IS AN ALKYL RADICAL HAVING 1 TO 4 CARBON ATOMS, -CN, PHENYL -CL AND -BR, AND (C) 0.1 TO 40 WEIGHT PERCENT OF A PARTIAL ESTER OF (1) AN A-B-OLEFINIC UNSATURATED POLYCARBOXYLIC ACID OR ANHYDRIDE THEREOF HAVING FROM 4 TO 10 CARBON ATOMS AND (2) A HYDROXYL NONIONIC DISPERSING AGENT HAVING THE FORMULA H-(O-CH2-CH2)N-O-R9 WHEREIN R9 IS ANY HYDROPHOBIC GROUP HAVING 6 TO 30 CARBON ATOMS OR MORE IN THE HYDROPHOBIC GROUP AND N IS AN AVERAGE NUMBER OF FROM ABOUT 0 TO ABOUT 60. THESE COMPOSITIONS ARE USEFUL AS ADHESIVES, EXTRUSION COATINGS OR GASKETING MATERIAL. IN LATEX FORM, THEY ARE ESPECIALLY USEFUL AS ADHESIVE BINDERS IN MINERAL PIGMENT COATING COMPOSITIONS FOR PAPER, PAPERBOARD AND PAPER PRODUCTS. A SPECIFIC EXAMPLE IS A TERPOLYMER OF (A) ETHYLENE, (B) VINYL CHLORIDE, AND (C) ETHOXYLATED TRIDECYL MALEATE HALF ESTER CONTAINING 9 TO 10 ETHOXY GROUPS IN THE ESTER. THEY MAY ALSO BE APPLIED AS THE ONLY PAPER TREATING AGENT TO IMPROVE THE BARRIER PROPERTIES AND GREASE RESISTANCE OF THE PAPER OR PAPERBOARD.

lint. Cl. DZlh 1/28 U.S. Cl. 117-155 UA No Drawing. 14 Pages Specification This invention relates to terpolymers containing (a) 2 to 60 weight percent of an olefinic unsaturated hydrocarbon compound, (b) 40 to 98 weight percent of a vinyl type compound having the formula wherein R is hydrogen, methyl or halogen and R is hydrogen or a carbonyl type residue such as COOR or OCOR, where R, is an alkyl radical having 1 to 12 carbon atoms, and R is an alkyl radical having 1 to 4 carbon atoms, CN, phenyl Cl and Br, and (c) 0.1 to 40 weight percent of a partial ester of (1) an a-fl-olefinic unsaturated polycarboxylic acid or anhydride thereof having from 4 to 10 carbon atoms and (2) a hydroxyl nonionic dispersing agent having the formula H-{OCH2CHz n wherein R is any hydrophobic group having 6 to 30 carbon atoms or more in the hydrophobic group and n is an average number of from about 0 to about 60. These compositions are useful as adhesives, extrusion coatings or gasketing material. In latex form, they are especially useful as adhesive binders in mineral pigment coating compositions for paper, paperboard and paper products. A specific example is a terpolymer of (a) ethylene, (b) vinyl chloride, and (c) ethoxylated tridecyl maleate half ester containing 9 to 10 ethoxy groups in the ester. They may also be applied as the only paper treating agent to improve the barrier properties and grease resistance of the paper or paperboard.
